Four science instructors at East Coast Career College ask you whether they can access a particular log file from their home directories. They explain that they update a log file in the /workgrp/project directory weekly, and they dont want to change out of their home directories every time they want to view or edit the file. In addition, they want the log file in their home directories to be called myjournal. How would you create links to the log file so that each instructor can access the file from his or her home directory, using the following criteria:

Scientist 1: Michio Home directory: /home/michio

Scientist 2: Neil Home directory: /home/neil

Scientist 3: Marty Home directory: /home/marty

Scientist 4: Ellen Home directory: /home/ellen

The log file is called sci.journal, and its in the /workgrp/project directory.

How would you limit the ability to modify the sci.journal file to the four individuals listed in part a.
